An efficient preparation for arylethynyl sulfides 1 and bis(arylethynyl) sulfides 2 has been accomplished through a one‐pot, three‐step strategy that starts from arylethanonyl sulfides and bis(arylethanonyl) sulfides, respectively, without the use of various terminal arylacetylenes as substrates. When lithium hexamethyldisilazane (LHMDS), ClP(O)(OEt) 2 , and LHMDS were sequentially added to a tetrahydrofuran solution of different substrates [arylethanonyl sulfides or bis(arylethanonyl) sulfides], 1 or 2 were obtained in moderate to good yields. The reaction procedure involves the formation of an enol phosphate and a subsequent base‐induced elimination.
